-Be itiknown thatl, ALInIoNgsn A. .Samsmx, a citizen of ythe United States, resid: ing at Chicago, in the county of @ook and I Sme ,'Oflllinois, have invented :certain new and eseiullmpwvemnts in Ceiling Lights, iofyvhioh the Ifolilow' is a specitieation. The present invention relates to `ceiling flight y,construetions,iand has for its rincipal 10 `the `Aprovfisml of a-.cei'ling `lig t which is fhah'cterized .fby certain novel improveinthefarrangelnent, mounting andzoperation lof the/movable ,sash portion.

ceiling 14 with the lower edge of the iframe [lushA lwith the `(boilingand Yfinished off gwith the =usua1itrim .15,Y The franieisprovided,

The movable sashes l1 and 12 are o-equal I' size, 4,and substantially fill the :opening the ltrame' l0 and overlie Vthe beading V16 when `Iarranged edge to edge in their closed ,position of .peripheral support .on shoulder 17=of the trame, l L [The Ineetingedges of the sashesare providedv withV offset complementary ftongues 21 which ,join Ito produce a .close kfit .of :the Sashes'when in their closed position.- v g IThe guide means 13 consistof twois aced lhorizontal guide .channels 22 positioned r`upon: the :shoulder k17 .against :the frame Vsides ,20,5and one vertical xguide lchannel -23 extending perpendicularly upwards from l oneo-qthe guide channels 2 2 .and positioned againstk theginner face of the-stile 19; The .guide .channels referred .tolare each z referably rectangular kin cross-section'and 'ormed with 4three closed ,sides Pand one centrally slottedr side,4 whereby to provide Ienclosed .roller tracks having: openings for :the passage thereinto Z:of vthe roller, axles. The lends of the `sashes 'opposite .to the '.interitting `ends are. rounded off ,along their lower edges 24 orxthe purpose hereinafter apparentand are [provided adjacent their extremities4 with V,brackets 25 in` which are mounted aligned -showing .the horizontalguides and .the sup- Y axles-26 c arryil'lg rollers 27.- The vaxles 26 lkextend horizontallyxthrou h the slots in the y:channels 22` 'and l:the ro 1ers 27 are contained with-in .the ,channels5 as shown in Eig. 3. 'I lheniiterfittingends 'of the sashes arerhinged togetheralongtheir lower edges rwitlntwo or lnorespaoed hinges 28, andare provided adjacent .corresponding 1edges of their upper surface with a spanning hinge tioaloliannel' an isthere providedvith a rol-1er 34. The pin has attached thereto, between the bracket/ .29 and the channel 23, a

coupling hook S5, which is removably secured to a complementary ring member 36 carried by the lower end of a supporting tape 37. The tape 37 operates onthe reel 38 of a. spring balanced device 39 secured to the stile i9,4 and serves to maintain the sashes in a state ot equilibrium in either a partly or fully open position of the same.

`The inter-fitting ends o't the sashes are also provided, adjacent the edges of their upper surfaces opposite to the hinge bracket 29, with a yoke 40 composed preferably of two short vends of chain which are attached to the sashes at spaced corresponding points and connected together with an Sflink 41. This yoke in turn is connected with a spring bala-nce device 4Q which is secured to the stile 18 and provided with a tape 43 and ring member 44 in the manner of the device 39.'

' The ceiling light is operated to assume either a partly or fully open position by the application of pressure to its under side at any point adjacent to the hinged portions ot the sashes.` The sashes being counterweighted as described, it will be understood lthat very little pressure is required in the operation.' As the hinged portions of the sashes are raised, being guided vertically by the roller 34 in the guide channel 23, the Jfree ends Yof the sashes approach each other, being guided in a common plane of the frame by the rollers 27 in the guide channels 22, and the two sashes assume an angular inverted V-sha'ped position. VThe sashes will remain'in any partly open position in which placed and may be moved, if desired, to a fully open position wherein the sashes are substantially folded together in a vertical position.

i The guide channel 23 is provided with a plurality of small transverse apertures 45 adjacent its upper extremity through any one of which the pin 46 may be inserted for the purpose of limiting, as may be desired, the extent to which the sashes vwill normally open. The upper extremity of the channel 23 is open, and is lower than the'height that the roller 34 will assume when the sashes are folded together in vtheir fully open position; in which position the roller will leave the channel 23, and the supporting tapes may then be disengaged from the sashes and-the sashes moved bodily to either end ot the frame, as shown by dotted lines inY Fig. 2.

In order to compensate for structural irl regularities in the spacing ot the horizontal guide channels 22, or warping of the supporting frame or the sashes, the axle pins of .the rollers 27 and 34 may be adapted for lengthwise movement in their sockets in the brackets 25 and 29, or may be provided with conical heads adapted to intert with similarly shaped central apertures in the rollers.` This construction of the pin heads and rollers is indicated in dotted lines in Fig. 3, and forms the subject-matter of a separate co-pending application.

lV claim:

`l. In aceiling light, a trame, two hinged sashes adapted to extend horizontally in the trame when in their closed position, means adapted to guide the tree ends of the sashes horizontally in the tra-me when the hinged ends of the sashes are moved vertically to told the sashes together in their open position, and a vertically extending guide associated with the frame for directing the hingedends of the sashes in their vertical movement.

2. In a ceiling light, a frame, twohinged sashes adapted to extendhorizontally in the vtrame when in their closed position, means 'gravity on the same whereby to maintain the sashes in equilibrium in any position which the same may be caused to assume.

3. In a ceiling light, a frame, two hinged sashes adapted to extend horizontally in the :trarne when'in their closed position, *rollers on the free ends ot the sashes, guides on the Jframe adapted to receive the rollers and thereby guide the tree ends of the sashes horizontally inV the frame when the hinged ends of the sashes are moved vertically to fold the sashestogetherv in their open position, and means actingV on the hingedv ends of the Vsashes in oppositionto the action of gravity on the'same whereby to maintain the sashes in any position which the same may be caused to assume.

4. In a ceiling light, a frame, two hinged sashes associated with the frame, and means adapted to guide the hinged ends of the sashes in a direction perpendicular to the plane oit the frame whereby the two sashes may be folded together, said means being adapted to permit the sashes to be released yfrom such guide engagement in the folded position of the same whereby the two sashes may be moved in unison parallel to the plane of the frame;

5. In a ceiling light, a frame, two hinged sashes adapted to extend horizontally in the frame when in their closed position, rollers yon the tree ends of the sashes, guides on horizontally in the frame when the hinged ends of? the sashes are movedl vertically to Y told thesashes together in their open position, a roller adjacent the hinged ends of thesashes, a guide extending vertically from the frame and adapted to receive the roller A`and thereby guide the hinged ends of the ment in the folded position of the same and sashes vertically from the frame, said vertmay be moved in unison to either end of the cally extending guide terminating short of frame.V 10 the uppermost position of its associated roll- Ill testimony whereof I have hereunto er whereby the roller will leave the guide Subscribed my llame.

in its uppermost position andthe sashes will be released from such guided engage- ALPHONSE A. SEBASTIAN.
